Prevention and treatment of dead seedlings of radish

Radish is widely planted in China, but the phenomenon of dead seedlings often occurs in the process of radish planting, which gives farmers a great headache. So what should we do about the dead seedlings of radish? The following editor for you to share the prevention and control of dead radish seedlings, let's take a look.

1. Rotation and stubble

Radish is not a suitable market for continuous cropping, so it is necessary to make a reasonable rotation and put the cropping system of crop rotation into practice. at the same time, it is necessary to reduce the frequency and amount of pesticide use, increase soil permeability, improve soil vitality and reduce drug residues of herbicides. After radish planting, it is necessary to strengthen the management, apply whatever elements are needed, and apply rotten as much as needed, increase the residue of fertilizer in the soil, restore soil vitality and improve the soil environment.

2. Temperature control

Radish germination temperature is suitable for 20 degrees attention, the seedling stage can withstand a low temperature of about 5 degrees, but also can endure a long time of subzero low temperature, but a short period of high temperature and low temperature for radish seed germination is extremely favorable, leaf growth suitable temperature is 20 degrees, fleshy root growth temperature is about 16 degrees, once the temperature is less than 20 degrees, the growth of radish is weak, the yield is low. Therefore, plastic film mulching can be used in the later stage of radish cultivation, so that the radish seeds can blossom without the problem of dead seedlings. It is necessary to disinfect the seeds and pay attention to the temperature adjustment during the seed growth period.

3. Fertilizer use

Fertilizer is very effective in preventing dead radish seedlings, and special foliar fertilizer can be used to prevent dead radish seedlings from rotting roots. In the three stages of herbicide application after radish harvest, three leaves in one heart after emergence, and expansion of the lower part of the root system, the unexpected effect can be obtained by spraying on the ground and leaves three times. Fertilizer should be used reasonably, what elements are needed to apply appropriate fertilizer, and the amount of fertilizer should be carried out according to soil fertility and radish growth. At the same time, spraying special foliar fertilizer combined with new high-fat film can not only increase soil permeability, improve soil vitality, but also reduce drug residues.

The above is the introduction of the prevention and control methods of dead radish seedlings, hope to help you, want to know more related knowledge, please pay attention to us.
